From the Adbusters team:
“Design is at war with itself. We are taught that design is about finding solutions. But the success of these solutions is judged so narrowly - Did it ooze desire? Did it shift units? – that we find ourselves implicated in problems far greater than the ones we solve. The time has come for a radical shift in priorities. We are now faced with some of the most daunting global challenges in human history. These are real targets, worthy of our problem-solving skills, ripe for our intervention. Yet those who have the vision to rise above national and political boundaries still have no symbol to rally under. We invite you to create a flag - free from language and well-worn clichés - that embodies the idea of global citizenship. A symbol that triggers pride and cohesion, whether worn on a backpack, displayed on a door, or flown on a flagpole. A symbol for anyone to declare membership in a growing and vital human cooperative. We invite you to prove that design has a real role to play in the fate of our world.
Submissions will be critiqued by a panel of prominent design professionals, then featured in Adbusters and supporting design publications. The winning flag will go into production, ready for flying by the patriotic citizens of Earth.
Deadline for entries is December 1, 2008.
Judges: Jonathan Barnbrook, Michael Bierut, Vince Frost, Steven Heller, Kalle Lasn, Rick Poynor and Dmitri Siegel."
